Answer:

True

Explanation:

This is essentially natural selection. If there is a population of giraffes and half of them have long necks and the other half have short necks, the ones with long necks will be more likely to survive because they will be able to reach more leaves on tall trees. This means the ones with short necks will be less likely to survive, so when the long neck giraffes reproduce, they will pass on the gene for a long neck to their offspring. Over time, there will be more and more long neck giraffes and fewer short neck ones.

This is just a silly example but it is actually have animals have evolved over thousands of years lol

What purpose does a fish ladder serve?

Whitepunk [10]

Answer: Option A

Explanation :

A fish ladder is also known as fish steps, fish pass or fishway.

It is built around waterfalls, dams and locks.

The purpose of building a fish ladder is to facilitate the natural migration of diadromous fishes.

A fish ladder helps the fish to pass through the barriers by leaping up or swimming through the low steps of the ladder and reach into the water on the other side.

Since, without the fish ladder the barriers will not allow the migration of fishes, it is essential to be built around the dams, waterfalls and locks.

Who is studying animals in the wild considered to be somewhat experimentally out of control

KIM [24]

Studying animals in the wild is considered somewhat experimentally out of control because of several reasons.

Explanation:

Study of wild animals can be done using several methods but none will be as effective as studying captivated animals. Using stationary cameras is a method to observe animals in the wild. The stationary nature of the camera makes it necessary for the animals to appear within the field of the camera.

This is difficult in places of low animal density. In addition to that placing camera at a longer distance to watch a larger area decreases the resolution of the images. When it comes to shallow water systems, the field imagery used to track the aquatic species frequently gets affected by issues like sun flicker.

Unmanned aerial vehicles can also be used to track and study animals in the wild. This is good alternative but filming through dense canopies or turbid water is a limitation. Bio loggers can also be used for animal tracking but it is limited by weight since it has to be carried by animals.
